Garda Sergeant Tania McCabe died just hours after giving birth to Adam and his twin brother Zach at Our Lady of Lourdes Hospital in Drogheda, Co Louth, in 2007.
Tragically Zach also passed away in his mother's arms, while Adam was rushed to the National Maternity Hospital at Holles Street in Dublin where he spent the first three months of his life.
Tania's husband, Aidan McCabe, also a garda, brought Adam to the Phoenix Park where they officially handed over two €42,000 incubators to staff from the two hospitals
And little Adam (5) could be a garda in the making as he borrowed Commissioner Martin Callinan's cap and gave a regulation salute to assembled photographers.
The foundation, set up in his mother Tania's name, which counts broadcaster Miriam O'Callaghan as its patron, has so far raised just over €100,000 and intends to continue fund-raising.
"Adam was born at 27 weeks and he was just slightly over a kilo in weight so that's less than a bag of sugar," recalled Mr McCabe.
"To see him today, he's fighting fit, he's super.
"Like a lot of people, I didn't know a lot about these special baby units. Somebody's niece, nephew, grandson, son, daughter could be in one in the future, but at least they'll be in one of these incubators," he said.
